I am in the process of running a water line from my well pump a garden bed about 75 feet away. I will have a separate shut off valve for this water line. At the garden end I will have two hose bibs. This will probably change eventually to drip irrigation or misting systems. Eventually this line will continue to bring water to a green house and other outbuildings that require very little water usage.
Do I need a type of check valve or back-flow preventer at the start of my line ? Or will a back-flow preventer on each hose bib be sufficient. Coming out of the well pump house I will 'T' the line with 1 line going to the house and 1 line going to the garden area.
I live very rural with no local restrictions.
